O'Neill has been the O'riginal California surf lifestyle brand since 1952, and this boardshort reflects that surf-first design approach, pairing stretch fabric with quick drying performance rather than a plain woven short.
Who It Is For
The above the knee, 19 inch length and stretch fabric suit anyone who wants to move freely while surfing, paddleboarding, or diving off a boat in South Florida's warm water, then walk straight into the sun without dragging a soaked, slow-drying short. The side zip pocket gives you a secure spot for a key or a card while you are out.
Wearing and Caring for It
Because the fabric is built with O'Neill Hyperdry DWR, it sheds water and dries fast, so you can wear it straight into the ocean and be comfortable back on dry land soon after. Rinse it in fresh water after saltwater or chlorine exposure to protect the stretch elastane and the zip pocket hardware, and hang it to dry rather than machine drying on high heat to keep the recycled fabric performing.
Why Shop This at Island Water Sports
Island Water Sports has fitted South Florida surfers since 1978, and we stock the Hyperfreak line because the stretch, quick dry, and recycled construction hold up to the saltwater and sun our customers put it through every day. Our team can help you confirm fit before you buy.
